Patent JP-H01278130-A (JP)
Title: Diversity receiving device
Inventor: MUROMOTO ATSUSHI
IPC: H04B7/02
Filed: 1988-04-30
Abstract: PURPOSE:To omit a defective synthesizing action and the signal interruption by detecting the level of the effective transmission signal included in each path and carrying out the automatic gain control. CONSTITUTION:The correlation outputs of correlators 15 and 25 are applied to the power detectors 16 and 26 and the square sum of the voltage of each top is obtained for detection of the original signal level of each path. A maximum power detector 5 detects the voltage of either one of both paths that has a higher signal level. Then the AGC voltage is applied in common to two AGC amplifiers 13 and 23 so that the detected voltage has a prescribed level. This negative feedback action keeps the output signal of the AGC amplifier of the path having a higher level at a constant level. Thus the gains are distributed in common to both amplifiers 13 and 23 for normalization. In such a way, the level of the effective transmission signal itself included in each path is detected for execution of the gain control. Thus it is possible to avoid a defective synthesizing action due to a malfunction of the gain control and the signal interruption.

Title: Pll circuit
Inventor: YAMASHITA NORIYUKI
IPC: H03L7/099
Filed: 1979-08-24
Abstract: PURPOSE:To prevent a variable frequency oscillator from being locked to the frequency other than a desired frequency, by controlling the circuit so that the voltage corresponding to the phase difference between the output of the variable frequency oscillator and the reference signal cannot exceed a prescribed range. CONSTITUTION:The collector current of transistor TR T7 is converted to a voltage by resistance RL and diodes D7-D9 and is supplied to hold capacitor C1 through emitter follower TR T34. The terminal voltage of capacitor C1 is supplied from pin terminal 13 to external low-pass filter 14 through TRs T37-T39, resistance R12, and the emitter follower. The output current of filter 14 is supplied to the base of TR T8 after the bias current dependent upon variable resistance RC is added. The collector current of TR T8 is transferred to the collector current of TR T9 through the diode consisting of TRs T40 and T41 and is further transferred to collector current IC (oscillation control current) of TR T1 through TR T<10>. The oscillation frequency of VCO8 is controlled by this control current and is locked to a desired frequency.
